The bottom end of the rotary shaft 311 is provided with an eccentric columnar body 33 and a bearing 34, which are received in a cavity 11 of the base 10. The vibration seat 20 is capable of being actuated by the motor 31 in motion to bring about a horizontal vibrating motion of a micro-amplitude high frequency.

The frame 40 is composed of a front support 41 and a rear support 42, which are fastened respectively at the bottom thereof with the vibration seat 20. The rear support 42 is provided with a seat 43 fastened therewith, whereas the front support 41 is provided at the top thereof with a handlebar 44. The front support 41 is provided with a seat block 45 which is in turn provided with a pivoting hole 451 and a fastening tube 46 fastened therewith such that the fastening tube 46 is corresponding in location to the pivoting hole 451. The fastening tube 46 is provided in the outer wall thereof with a rodlike guide portion 461 extending outward in the direction of the radius of the fastening tube 46.

The driving device 35 consists of the motor 31 and a tubular body 50. The driving device 35 and the vibration device 30 share the same motor 31. The rotary shaft 311 of the motor 31 is capable of driving a driving wheel 37 via a transmission mechanism 36 (gear). The tubular body 50 and a bearing 51 are engaged pivotally with the pivoting hole 451 of the seat block 45. The tubular body 50 is provided with a link disk 52 fastened therewith such that the link disk 52 is corresponding in location to the fastening tube 46. The link disk 52 is provided with a plurality of through holes 521. The tubular body 50 is further provided at another end thereof with a driven wheel 53 which is link with the driving wheel 37 by a transmission belt 38 which is pressed by an adjustable belt-pressing wheel 39. The tubular body 50 is driven by the motor 31 in motion to rotate in the counterclockwise direction of FIG. 1.

The pedal device 60 has a shaft 61, which is fastened pivotally with the tubular body 50 such that both ends of the shaft 61 are jutted out of the tubular body 50 as well as the shield 25 and are respectively fastened with a crank arm 62. The crank arm 62 is fastened with a pedal 63. The shaft 61 is provided with a hexagonal insertion portion 611 in proximity of the link disk 52. The link disk 52 has a plurality of through holes 521.

The over-running clutch 70 has a ratchet-like first element 71 which is provided with a hexagonal retaining hole 711. The first element 71 is fastened with the shaft 61 such that the hexagonal retaining hole 711 is engaged with the hexagonal insertion portion 611 in conjunction with a locating pin 74. The first element 71 is provided with a tubular second element 72 fitted thereover such that the first element 71 and the second element 72 are provided therebetween with a plurality of tooth gaps 712. Each of the tooth gaps 712 is provided therein with a rolling column 73 enabling the second element 72 to actuate the first element 71 to rotate simultaneously. In addition, the first element 71 is capable of revolving freely in relation to the second element 72. The second element 72 is provided in the outer wall surface thereof with a dial portion 721 extending outward in the direction of the radius of the second element 72.

The clutch device is composed of a turning member 80, a plurality of elastic elements 85, and a control member 90.

The turning member 80 has a disk 81 which is provided with a plurality of rodlike protrusions 82 and is fastened pivotally with the tubular body 50 such that the protrusions 82 are retained in the through holes 521 of the link disk 52. The turning member 80 is thus capable of being actuated by the link disk 52 to rotate along with the tubular body 50.

The elastic elements 85 are coil springs and are fitted over the protrusions 82 of the turning member 80 such that both ends of each of the elastic elements 85 urge the link disk 52 and the disk 81 of the turning member 80. As a result, the turning member 80 is urged to move away from the over-running clutch 70.

The control member 90 has a cylinder 91, which is fastened pivotally with the fastening tube 46 such that one end of the cylinder 91 is in contact with the turning member 80. The cylinder 91 is provided at another end thereof with an inclined side 911 capable of making contact with the guide portion 461 of the fastening tube 46. The cylinder 91 is further provided with a connection rod 92 extending therefrom such that the connection rod 92 is jutted out of the shield 25 via a slot 251 of the shield 25. The connection rod 92 is provided with a handle 93 fastened therewith.

Before using the exercise bike of the present invention, the handle 93 of the control member 90 is first pushed upward to one side farther from the seat 43 such that the cylinder 91 of the control member 90 and the turning member 80 are situated at one side closest to the overrunning clutch 70, and that the ends of the protrusions 82 of the turning member 80 are jutted out of the link disk 52 to press against the dial portion 721 of the second element 72 of the over-running clutch 70, as shown in FIG. 4. The user is seated on the seat 43 before the driving device 35 is started. In the present invention, both the driving device 35 and the vibration device 30 are started simultaneously in view of the fact that they share the motor 31. As soon as the driving device 35 is started, the tubular body 50 is driven by the driving device 35 to turn forward at a slow speed. In the meantime, the turning member 80 is actuated by the tubular body 50 in motion to rotate such that the second element 72 is actuated by the protrusions 82 of the turning member 80 in motion to turn forward. As the second element 72 is actuated to turn forward, the shaft 61 of the pedal device 60 is actuated to turn forward via the first element 71. As a result, both feet of the user of the exercise bike are actuated by the pedal device 60 to engage in the pedalling. In the meantime, the vibration seat 20 is driven by the vibration device 30 to generate the high frequency vibrational motion, which is then imparted via the frame 40 to the seat 43, the handlebar 44 and the pedal device 60 to bring about the massaging effect. In other words, the hips, the back, the hands and the legs of the user seated on the seat 43 are effectively massaged while the user is engaged in the pedalling exercise. However, the pedal device 60 may be intentional disabled while the user is massaged by the exercise bicycle. The pedal device 60 is disabled by pulling the handle 93 backward to one side near the seat 43 such that the cylinder 91 of the control member 90 is urged by the elastic elements 85, and that the inclined side 911 is in contact with the guide portion 461, and further that the protrusions 82 of the turning member 80 are no longer jutted out of the through holes 521 of the link disk 52, thereby resulting in the disengagement of the turning member 80 with the second element 72, as shown in FIG. 5. As a result, the shaft 61 of the pedal device 61 is idled.

The embodiment of the present invention described above is to be deemed in all respects as being merely illustrative and not restrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scopes of the following appended claims.
